7th century. As an aged Irish priest Gerebernus accompanied
Saint Dympna (f.d. today),
whom he had baptized in her infancy, to Belgium and
shared in her martyrdom at Gheel. He is the patron saint of the village
of Sonsbeck (Santbeck), Cleves, in the Rhineland, Germany, where his
relics are enshrined, except for his head, which is in Gheel. Curiously,
he was the subject of "holy robbers of Xanten" who specialised in
stealing holy relics, although they were unable to remove those of
Dympna. His intercession is sought against gout and fever
(
Benedictines,
D'Arcy,
Husenbeth).
